THE EFFECT OF TEACHING TECHNIQUES AND STUDENTS PERSONAL TRAITS ON STUDENTS ACHIEVEMENT IN DESCRIPTIVE WRITING

The objectives of this experimental research were to investigate whether: 1) students achievement in descriptive writing taught by using roundtable teaching technique was higher than taught by using clustering teaching technique. 2) students achievement in descriptive writing with introvert personal trait was higher than that students with extrovert personal trait, 3) there was interaction between teaching techniques and personal traits on students achievement in descriptive writing. The population of this research was the students in grade XI of SMA Negeri 1 Sidamanik 2013/2014 school academic year.The total number of population were 280 students. There were 80 students selected as sample of this research by applying cluster random sample technique. The research design was experimental research by using factorial design 2x2. The students were divided into two experimental groups. The experimental group 1 was treated by using roundtable teaching technique and experimental group II was treated by using clustering teaching technique. The questionnaire was conducted for classifying the students upon the introvert and extrovert personal traits. Students achievement in descriptive writing was measured by using writing test. The data were analyzed by applying two-way analysis of variance (ANOVA) at the level of significance α= 0.05. The result reveals that (1) students achievement in descriptive writing taught by using roundtable teaching technique was higher than that taught by using clustering teaching technique, with Fobs= 4.59>Ftab=3.97, (2) students achievement in descriptive writing with introvert personal trait was higher than that with extrovert personal trait with Fobs= 4.90>Ftable=3.97, (3) there is interaction between techniques and personal traits on students achievement in descriptive writing with Fobs=6.58>Ftable=3.97. After computing the Tuckey-Test, the result showed that introvert students got higher achievement if they were taught by using roundtable teaching technique while extrovert students got higher achievement if they were taught by using clustering teaching technique.
